Surveillance footage shows a deer crash through a glass door into the school. It is quickly followed by two others.

Two dogs can be seen pacing outside. Eventually, the dogs jump through the broken glass and continue the chase.

Police say animal control was able to catch the two dogs, neither of which were wearing collars. One is a German Shepherd, and the other is believed to be a black lab mix.

Police say one of the deer died from its injuries in the attack, and the other two were injured so severely they had to be euthanized.

Anne Arundel County Schools spokesperson Bob Mosier says classes had to be canceled because it took a long time to clean up the school. He said crews weren't done until noon.

Mosier says classes at both Southern Middle and Lothian Elementary, which currently shares the property, had to be canceled. He says it remains to be seen if the day will have to be made up by students there. Students in all of Anne Arundel County have already had eight days off school due to winter weather.

Mosier says Maryland Student Assessment tests will go on as scheduled when classes begin again Tuesday.
